Where do you guys go to fill up your CO2 tank and how much does it normally cost for 5lb tank? I'm located in Gilbert.
I ended up getting the Deltec PF501 reactor with a Milwaukee SM122 PH controller. Bought it used from another reefer getting out. Still trying to figure things out. How do you check the P.H. in the tank when the PH probe is in the reactor? Also is it safe to increase the output flow from drip to slow flow? My calcium was at 350 before and still at 350 2 days now.
I thought you need a second probe in the tank to measure the PH.
Skip are the deltecs similar in operation to a koralin???
